Wehrli 06-10 Duramax LBZ/LMM Thermostat Housing Kit For Dual CP3 - WCFab Red

If you're working on a 2006-2010 Duramax LBZ or LMM, especially one set up for dual CP3 fuel pumps, this Wehrli Custom Fabrication thermostat housing kit is a smart upgrade. It replaces the stock upper radiator hose and coolant return pipe with a new routing that goes up and forward from the thermostat. This change makes it much easier to get to the driver-side fuel system components, which is a big help during maintenance or upgrades. It also creates more space if you're planning to install a larger aftermarket turbocharger, like the race cover or SXE style turbos. Plus, it gives your engine bay a cleaner, more updated look.

This kit is CNC machined from solid billet aluminum for a strong and well-built housing. It includes the coolant pipe, silicone boots, and t-bolt clamps needed for installation. While it's designed for dual CP3 setups, it's also compatible with dual alternator setups. It's a good choice if you're looking to improve access and clearance for performance modifications on your Duramax.

This kit is designed to work with specific aftermarket turbochargers and dual fueler systems. It replaces GM part numbers 19330105, 15792824, 25833204, and 97361881. Always refer to the manufacturer's installation instructions for complete details on compatibility and setup.
